![]() 1 or 2 won't work (fbi will 'cache' them even though you set cache 0 = only 3+ will force it to actulaly fetch the files) With 'cache = 0', 3 is the minimium to get fbi to actually fetch each of the 3 photos in turn (which, of course, are all aliased to the same 'master' so it ends up showing the exact same photo 'all the time'). You then launch fbi to 'cycle for ever' (rather than 'display once and stop'). symbolic links) to the same 'master' photo. You set up fbi to cycle through 3 'dummy' photos, all 'pointing' (using alias command 'ln -s' i.e. Yes, I know this is an old 'tread'', however it seems people do still use fbi so I thought I would 'post' my PhotoFrame 'final solution'. If (waitpid(pidProcess, &iReturn, WNOHANG) = pidProcess) NB don't be tempted to COPY new.jpg to d.jpg (fbi will show 'corrupted' data on screen as the file it's in the process of loading is overwritten by the cp)Ĭode: Select all pid_t pidOldJPGDisplay, pidNewJPGDisplay (the -t sets it to run 'for ever' on a 3 second cycle over the 3 images - so changing d.jpg should result in the new image appearing within 1s) fbi -d /dec/fb0 -a -noverbose -t 3 -cahcemem 0 d.jpg a1.jpg a2.jpg fbi has to be started with (at least) 3 images, since even with -chachemem 0, fbi will 'cache' 2 images (and thus never load the 'change')Įg. (so my slide show will 'pause' as the 'display a new image' (background task) checks for a button push before changing the alias to a new image) When you want to 'display a new image', make d.img an alias of the new image (ln -s -f new.jpg d.jpg) Make a1.jpg and a2.jpg both 'alias' of d.jpg (ln -s -f d.jpg a1.jpg, ln -s -f d.jpg a1.jpg) I set fbi to 'loop for ever' showing 3 'static' image names, d.jpg, a1.jpg, a2.jpg (see note at end) My requirement was to 'pause' a fbi slideshow, keeping the current image on display before moving seamlessly to the next = I expect my 'cunning trick' with soft links (alias) will help you. You can 'loop' it on a single image, and then 'killall fbi' (to force a clean up) just fine - and then re-launch for the next image - however, when you 'kill' it, the current image is removed from the screen and the screen reverts to whatever (typically, the status text from the log-in) If you set it to show a single image, fine - but it fails to clear up correctly (it has a RAM leak ?) so if you invoke it multiple times to show many images in succession and after 50 or so and the Pi crashes with insufficient RAM (it doesn't support stdin, so you can't 'pipe' it images to display) The first step is to enter the command given below.Fbi won't 'quit' cleanly (or at all) = It won't run in the background, so if you set it to 'loop' through a dir it will show all the images (that exist when it is launched = it does not recheck the dir contents later) just fine but that user log-in is then locked to fbi. Open up a new Terminal session through the Activities menu or by pressing Ctrl + Alt + T on your keyboard. #Terminal image viewer installSome of the viewing modes are slideshow, montage, multiview, and index.īefore we get to how you can use these awesome features, let’s install the package. But before that, let’s talk about some of the features this image viewer has to offer.įeh supports various image-viewing modes, file lists, configurable keyboard and mouse shortcuts, signals, image captions, terminal input, and much more. It can be installed through the official Ubuntu repositories as we’ll show you shortly. That roughly covers all the main points of this guide, so without any further ado, let’s get into it! Using Fehįeh is a nifty little tool that you can install on your system to show images in the Terminal. Let’s break down our discussion in the form of a list for the sake of accessibility. Mostly our focus will be on installing and using third-party utilities, except for one method where you can use a built-in command to achieve the same task. We will show you several different methods you can use to display images in the Terminal. This brings us to the purpose of this guide – we will demonstrate how you can show images in the Terminal on Ubuntu. #Terminal image viewer fullHowever, the Terminal isn’t able to show graphical images like applications with full GUI interfaces. Most Linux users are big fans of the Terminal and therefore use it to perform everyday tasks on their operating system. ![]()
